Atomimassoja tarvitaan, jotta voitaisiin esimerkiksi tutkia atomin ytimen rakennetta ja sidosenergioita. Kaikkia ytimi\u00e4 ei kuitenkaan ole mahdollista saada mitattua nykytekniikoilla, vaan tarvitaan massaennusteita. T\u00e4ss\u00e4 pro gradu -ty\u00f6ss\u00e4 vertailtiin teoreettisista atomimassaennusteista ja Atomimassaevaluaatiosta (AME2003) saatuja massojen arvoja JYFLTRAP:lla mitattuihin massoihin.\n\nTy\u00f6t\u00e4 varten laskettiin kokeellisten ja teoreettisten massavajeiden erotukset, kahden neutronin sidosenergiat, teoreettisten ja kokeellisten S2n-arvojen erotukset ja neutronin kuoriaukkoenergiat neutroniluvuille N = 28, 50 ja 82. Lasketuista arvoista tehtiin kuvaajat, joiden avulla malleja pystyttiin vertaamaan kokeellisiin arvoihin. Massavaje-erotuksista ja kahden neutronin sidosenergiaerotuksista laskettiin lis\u00e4ksi keskiarvot, keskipoikkeamat ja neli\u00f6lliset keskiarvot eli rms-poikkeamat, joista my\u00f6s pystyttiin tarkastelemaan mallien toimivuutta.\n\nSek\u00e4 kuvaajien ett\u00e4 laskettujen rms-poikkeamien perusteella voidaan todeta, etteiv\u00e4t atomimassaennusteet mallinna kunnolla kokeellisia tuloksia. Ty\u00f6n perusteella parhaiten toimivimmat mallit sek\u00e4 massavajeille ett\u00e4 S2n-arvoille olivat Duflo-Zuker ja HFB-17. Kokeellisia massavajearvoja mallinsivat heikoimmin parillis-parillisille ytimille arvoja antavat mallit GCM ja EDF, joka oli heikoin malli my\u00f6s S2n-arvoille.
