“…95 Pd m was the first of this type of isomeric state measured at JYFLTRAP, and it confirms the results from in-beam γ spectroscopy [26]. The excitation energy of 53 Co m [25] yields a more precise value for the mirror energy difference in the T = 1/2 pair at A = 53.…”

“…The time behaviour of the beta particles at A = 90 after the IGISOL dipole magnet confirms that the ground state is the 8 + state with a half-life of around 50 s. The excitation energy of the isomer was determined by measuring the isomeric and ground states separately against the reference 86 Kr. JYFLTRAP has also been capable of measuring the masses and excitation energies of high-spin, spin-gap isomers 53 Co m (19/2 − ) [25] and 95 Pd m (21/2 + ) [13]. The measured excitation energies are collected in Table 1.…”

Masses of nuclides involved in astrophysical rp and ν p processes have to be known precisely in order to model these processes reliably. Mass excesses for 90 ground state and 8 isomeric states of neutron-deficient nuclides have been determined with a precision of better than 10 keV with the JYFLTRAP double Penning trap mass spectrometer at the Ion-Guide Isotope Separator On-Line facility in Jyväskylä. Highlights of the measurements related to nuclear astrophysics are given. Some of the measured isomers, such as 53 Co m , 90 Tc m , and 95 Pd m , and implications for the excitation energy of the 21 + isomer in 94 Ag are briefly discussed.

“…There are two main indirect methods, [9]. Recently, the mass of Co 53 m was precisely determined to be −39482.9(16) keV at JYFLTRAP [10]. Therefore, the mass of Fe 52 which is the daughter nucleus of the proton decay of Co 53 m can be determined by the proton-decay energy of Co 53 m .…”

Nuclear mass continues to be of great importance for various aspects of nuclear physics, for instance, it is the basic building blocks of nuclear structure and nuclear astrophysics. In the study of nuclear structure, the mass of nucleus is an important parameter to validate the model theories and provide a limitation on parameters of theories. In nuclear astrophysics, masses of many nuclei far from line of stability play a vital role in the calculation of stellar nucleosynthesis. Since there is difficulties in measuring the key reaction of nuclear synthesis directly, the precise nuclei mass data can help us judge the importance of each possible nuclear synthesis path. Fe is indicated as a waiting point in stable nuclear burning on an accreting neutron star [5]. Its proton capture rate, which has a direct correlation with its mass, is one of the most important nuclear physics input parameters for the calculations of steady state burning on an accreting neutron star. Therefore, the mass of Fe 52 is an important input parameter in both nuclear structure and nuclear astrophysics.Mass measurements are pursued worldwide. There are a variety of ways that can determine the nuclear mass. The methods of measurement can be classified into two groups, direct and indirect method. The indirect measurement is an important way to determine the masses of nuclei, especially for the nuclei where the direct measurement is very difficult. There are two main indirect methods, Article available at

“…Combined with our new result about 53Com proton-decay energy and the mass of 53Com taken from Ref. [10], the mass excess of 52Fe was calculated as ME(52Fe) = ME(53Com) -ME(p) -£ c.m. = -48 330(8) keV in which ME is the mass excess of the nucleus and £ c m. is the proton-decay energy.…”

The proton decay ol 51Co'"(3174.1 keV, 19/2 ) was investigated via the fragmentation of a 58Ni primary beam. The proton-decay energy was determined with an improved precision to be 1558 (8) keV. With this new result and the mass o f 53Co'", the 52Fe mass excess was derived to be -4 8 330(8) keV, which is in good agreement with the AME12 value. A new recommended value of -48 331.6 (49) keV is given.
