All solid phases of bismuth under pressure, but one, have been experimentallyfound to superconduct. From Bi-I to Bi-V, avoiding Bi-IV, they becomesuperconductors and perhaps Bi-IV may also become superconductive. Toinvestigate the influence of the electronic properties N(E) and the vibrationalproperties F({\omega}) on their superconductivity we have ab initio calculatedthem for the corresponding experimental crystalline structures, and using a BCSapproach have been able to determine their critical temperatures Tc obtainingresults close to experiment: For Bi-I (The Wyckoff Phase) we predicted atransition temperature of less than 1.3 mK and a year later a Tc of 0.5 mK wasmeasured; for Bi-II Tc is 3.9 K measured and 3.6 K calculated; Bi-III has ameasured Tc of 7 K and 6.5 K calculated for the structure reported by Chen etal., and for Bi-V Tc ~ 8 K measured and 6.8 K calculated. Bi-IV has not beenfound to be a superconductor but we have recently predicted a Tc of 4.25 K.
