Astrophysics II and PP Class (Group A)

Dear Fourth Sem students,

I will take Astrophysics II class during 12:00-13:00 and Particle Physics class to group A during 13:30-14:30 today. 

Yesterday I took PP class to group B. I derived Faxen & Halzmark formula (scattering amplitude using Bauer's formula) assuming finite range potential (real one) and elastic scattering. When we calculated total reaction cross-section, we come up with interesting conclusion named as optical theorem. This theorem advocates the possibilities of total scattering cross-section in the forward direction. Due to this, there might be a possibility of complex potential, leading inelastic scattering in which reaction (nuclear) can not be avoided! We have calculated reaction cross-section as well. 

In Astrophysics class, I will discuss CNO reaction and triple alpha process. Find pdf file of astrophysics class here. 

See you.

Re: Online B.Sc CSIT Demo

Thanks a lot. It is sufficient for demo.  I will call local server host today. After meeting with them, I will call you.  On Mon, Feb 8, 2021 at 11:50 PM Sagar < searchbbc1881@gmail.com > wrote: Dear Sir, I have attached a demo of an Online application form submission system for B.Sc csit students. More improvements can be done with the styling and coding part. Due to time constraints, I have made a very necessary part here.  This video explains both the students and administrators part of the system.  -- ----------------------------------------- Prof. Dr. Binil Aryal Dean Institute of Science & Technology (IoST) Tribhuvan University, Kirtipur, NEPAL Tel. 00977 9803228105 (mobile)       00977 14330469 (office) http://www.tucdp.edu.np/index.php ------------------------------ ** Senator: TU Assembly ** Member: Academic Council, TU ** Member: S&T Cluster Committee, UGC ** Member: Research Committee, KU ** Member: Research Committee, IoE ** Member: Physics Subject Committee...

Talk Reminder: Today @ 12:30 (Seminar Hall)

Dear students, Mr. Ramesh Mainali , Ph.D. Candidate at Steward Observatory, University of Arizona, USA is going to deliver a talk on ' Spectroscopy of galaxies in the first billion years of cosmic time ' on 24 May 2018 at 12:30 (Seminar Hall). Mr. Mainali   remained one of the brilliant students of CDP in the past. He is working with a highly compititive research group. I would like to inform you that, according to National Science Foundation (NSF) ranks the University of Arizona (Mr. Mainali's University)  No. 1 in Astronomy and Astrophysics research ,   No. 22 overall Research Ranking ,   No. 45 Worldwide Ranking , according to the Center for University World Rankings. UA is also one of the   USA's top producers of Fulbright Scholars . All interested are invited to attend the talk.  Find the detail about the talk in the announcement.  Regards -- ----------------------------------------- Prof. Dr. Binil Aryal Head Central Department of Physics Tribhuvan Univers...

Re: Online entrance application

Thanks vai. I have viewed mp3, it is perfect! The only thing is >> where the data (data sent by students) will be hosted? >> is there possibility to divert data of students in our official mail as pdf? >> admit card will be sent to the students only after verification.  Best wishes!

I have asked some vendors about it and they have also asked for some time ...
