This change made it work like a charm. In the present work, the classical Bethe-Weizsäcker (BW) mass formula with five energy terms is revisited and updated. Over 2 lectures and 1.5 hours of content! According to my undergraduate notes, E B should be about 8MeV per nucleon, but as far as I can tell, that's using the "Wapstra" values from the table. They differ in terms of charge - the proton is positively charged whereas the neutron is uncharged - and rest mass - the RM of a neutron is about 1.29 MeV greater than that of a proton.

Lecture 2 The Semi Empirical Mass Formula SEMF . We use the least-squares adjustments on the binding energy of 2497 different nuclides from the last update of the atomic mass evaluation, AME2016 published in March 2017, to provide a new set of energy coefficients of the mass formula. 1 and 2. ): Nuclear stability, mass parabolas [Yip] pp. 12/1-3 Sopan Ashram Chakratanpur, Nankari IIT Kanpur, Uttar Pradesh, India - 208016 hcverma@iitk.ac.in www.hcverma.in Lecture-02-Nuclear Size. Again Mathematica can help here. 51-58; read carefully, and try the practice problems. The dependence of B/A on A (and Z) is captured by the semi-empirical mass formula. Nuclear and Particle Physics : Basic nuclear properties-size, binding energy, angular momentum, parity, magnetic moment; Semi-empirical mass formula and applications. Weight.

Transcribed image text: a4 (a) (Summer 2016 Q2(b)) A fit of the Weizsäcker semi-empirical mass formula to binding-energy data for heavy nuclei yields the following values for the parameters in the formula: av " 15.8 MeV, as 17.8 MeV: ae-071 1 MeV, aom-23.7 MeV: a 0, ±1 1.2 MeV (as appropriate) 0) Calculate the binding energies of americium-241(Am) and neptunium-237(Np). 0 a MeV 8 . This change made it work like a charm. In the present work, the classical Bethe-Weizsäcker (BW) mass formula with five energy terms is revisited and updated. Over 2 lectures and 1.5 hours of content! According to my undergraduate notes, E B should be about 8MeV per nucleon, but as far as I can tell, that's using the "Wapstra" values from the table. They differ in terms of charge - the proton is positively charged whereas the neutron is uncharged - and rest mass - the RM of a neutron is about 1.29 MeV greater than that of a proton.
