| Aug 27, 2016 at 13:16 | comment | added | Armin | @PhilCsar but if you are looking at some kind of spectrum, i think a fouriertransform is the way to go... anyway, good luck! | |
| Aug 27, 2016 at 13:13 | comment | added | anonymous | im trying it in my original problem and its still running. i have an idea on what the answer should be so ill know exactly if it helps :D | |
| Aug 27, 2016 at 13:11 | comment | added | Feyre | @PhilCsar In that case, does MinRecursion -> 20, MaxRecursion -> 200, WorkingPrecision -> 50 not help? | |
| Aug 27, 2016 at 12:57 | comment | added | anonymous | im pretty sure that theres nothing wrong in the unit conversion. also, what I posted is something that just looks similar to my original problem and I cant post my original problem here for particular reasons. | |
| Aug 27, 2016 at 12:48 | comment | added | Armin | @PhilCsar actually... if you consider a smaller energy, the integral is non-zero (numerically). Just fishing in the dust here: are you trying to do something with electron wave packages in natural units? if so, you may have to check your unit conversion... in other words: what is the origin of your computation? | |
| Aug 27, 2016 at 11:38 | comment | added | Armin | think so as well.... but not 100% sure | |

| Aug 27, 2016 at 11:36 | comment | added | Feyre | Which means 0, using NIntegrate[..,MinRecursion -> 20, MaxRecursion -> 200, WorkingPrecision -> 50] also yields 0 (3.5354832 ...*^-23 - 2.3618059 ...*^-24 I). The Integral is 0. | |
