Hello Ashot:
Somehow even Jan Bernauer did not mention much about this work. I just took a quick look, and their results are in better agreement with the PRad fit.

Best, Haiyan

Dear Ashot,

The paper I was speaking about is:

https://urldefense.proofpoint.com/v2/url?u=https-3A__nam11.safelinks.protection.outlook.com_-3Furl-3Dhttps-253A-252F-252Fjournals.aps.org-252Fprc-252Fabstract-252F10.1103-252FPhysRevC.106.044610-26data-3D05-257C02-257Chaiyan.gao-2540duke.edu-257Cc377941c54a8422e9d1f08de29304dbd-257Ccb72c54e4a314d9eb14a1ea36dfac94c-257C0-257C0-257C638993484610776603-257CUnknown-257CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ-253D-253D-257C0-257C-257C-257C-26sdata-3Dzk9SYGrYrcxJxwt8-252BFliCt7NS2Pig2SW-252F8pnqWT62aw-253D-26reserved-3D0&d=DwIGaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=V3XNY-MaMKN2LuAaTdObrA&m=oosjxsZaN9Gcq4x9-K3gOa-hx4fhePCHwCzeuoeHV5x4azGRA7fLcgexBIhP2s9d&s=Q-0Uu2zNXvCxLHb6pReyQnBOw0qUhIYBmsbkb8rexD0&e= <https://urldefense.proofpoint.com/v2/url?u=https-3A__journals.aps.org_prc_abstract_10.1103_PhysRevC.106.044610&d=DwIGaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=V3XNY-MaMKN2LuAaTdObrA&m=oosjxsZaN9Gcq4x9-K3gOa-hx4fhePCHwCzeuoeHV5x4azGRA7fLcgexBIhP2s9d&s=m6XuJw5eedwpHbjZMJ2eC_Pp-TEjgGtbECM-iGcmaeg&e= >

if you check figure 8, you can see their claim that their new data is
more compatible with PRad than with previous A1 measurments.

Best regards

Adam
