The evaluated experimental data are presented for 15 known nuclides of mass 100 (Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In, Sn). High spin excitations are known for {sup 100}Sr, {sup 100}Zr, {sup 100}Mo, {sup 100}Tc, {sup 100}Ru, {sup 100}Rh, {sup 100}Pd, {sup 100}Ag, and {sup 100}Cd. The neutron capture data are available for {sup 100}Tc and {sup 100}Ru. Particle transfer data exist for structures in {sup 100}Nb, {sup 100}Mo, {sup 100}Tc and {sup 100}Ru. The two-neutrino {beta}{beta} decay mode in {sup 100}Mo is fully established with measured half-life and population of the g.s. and 1130,0+ state in {sup 100}Ru. The absolute energy of the isomer in {sup 100}Nb is now well established from recent Penning-trap mass measurements. Excited state data are nonexistent for {sup 100}Kr, {sup 100}Rb and {sup 100}Sn; and only one excited state is known in {sup 100}In. Except for isotopic identification, no information is available for the decay of the {sup 100}Kr isotope and very little is known about the decay properties of the {sup 100}Sn isotope. In the case of {sup 100}Pd, there are many recent studies of high-spin structures but the agreement in the orderings of the {gamma}-ray cascades and {gamma}-ray inventory between various studies remains poor at high (>9 MeV) excitation energies. The energy difference between the g.s. an isomer in {sup 100}Y has recently been precisely measured in Penning-Penning-trap mass measurements, however, the assignments of the two previously known half-lives and J{pi}'s to the respective states (g.s. and the 145-keV isomer) in {sup 100}Y remains to be established. Static moments in {sup 100}Y have also been recently measured for one of these states in {sup 100}Y but it is not definitely known as to which of the two states (g.s. or the isomer) is connected with these measurements. This work supersedes earlier full evaluations of A = 100 by 1997Si09, 1990Si05 and 1974Ko37.
